PT100 temperature transmitter, SBWZ thermal resistor temperature transmitter is a field-mounted temperature transmitter unit in the DDZ-S series of instruments. It adopts a two-wire transmission method (two wires as power input and a common transmission line for signal output). Convert the thermocouple and thermal resistor signals into input electrical signals or measured temperatures or linear 4-20mA output signals. The transmitter can be installed in the junction box of the thermocouple and thermal resistor to form an integrated structure with it. As a new generation of temperature measuring instruments, it can be widely used in industrial sectors such as metallurgy, petrochemicals, electricity, light industry, textiles, food, national defense, and scientific research.

2. Features of PT100 temperature transmitter
1. It adopts an epoxy resin sealing structure, so it is shock-resistant and temperature-resistant, and is suitable for installation and use in harsh field environments.
2. It is installed on-site in the junction box of the thermal resistor and thermocouple, and directly outputs 4-20mA, which not only saves the expensive compensation wire cost, but also improves the anti-interference ability of the signal during long-distance transmission.
3. Độ chính xác cao, low power consumption, wide operating temperature range, stable and reliable operation.
4. The range is adjustable and has a linear correction function. The thermocouple temperature transmitter has an automatic cold end compensation function. It has a wide range of applications. It can form an integrated field installation structure with thermocouples and thermal resistors, and can also be installed in the detection equipment as a functional module.

III. Main technical indicators of PT100 temperature transmitter:
1. Input: thermal resistor Pt100, Cu50, Cu100
Thermocouple K, E, S, B, T, J, N
2. Output: Output 4~20mA DC signal within the range, which can be linear with the output resistance signal of the thermal resistance thermometer, and can be linear with the input temperature signal of the thermal resistance thermometer. It can be linear with the millivolt signal of the thermocouple input, and can also be linear with the input temperature signal of the thermocouple thermometer.
3. Basic error: ±0.2%, ±0.5%
4. Transmission mode: two-wire system
5. The minimum working power supply voltage of the transmitter is 12V, the maximum is 35V, and the rated working voltage is 24V.
6. Load: The limit negative load resistance is calculated as follows
RL (max) = 50 × (Vmm-12)
That is, the load resistance can be selected in the range of 0 to 600Ω at 24V) Rated load 250Ω.
Ghi chú: For adjustable range transmitters, the zero point and full scale need to be repeatedly debugged when changing the range; the thermocouple type transmitter must be preheated for 30 minutes before debugging.
7. Ambient temperature influence ≤0.05%1℃
8. Normal working environment:
Một. Ambient temperature -25℃～+80℃
b. Relative humidity 5%～95%
c. Mechanical vibration f≤55Hz amplitude＜0.15mm
